Guns, Dogs and Blades QnA

So I just got home from armors school on the AR platform. Unbeknownst to me the primary instructor turned out to be no less than Mike M the Founder and owner of Sons of Liberty Gun Works. He is an industry icon and truly innovated all things AR. When I saw him I envisioned a two day infomercial for his Company. Turned out the exact opposite. Not once did he pump or push his own product. His knowledge of the metallurgical aspects is phenomenal. Holy smokes what a resource of knowledge. He answered every question and endured all of our ineptitude! Just a great class, i had no idea how many teeny tiny springs there were in an AR. The classroom has springs from one end to the other! Guaranteed!
